DETAILED DESCRIPTION OF THE PRESENT INVENTION
The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description is taken with the drawings making apparent to those skilled in the art how the forms of the present invention may be embodied in practice.
FIG. 1 depicts a handling door 1 for an industrial building comprising a metal framework 2, a flexible apron or curtain 3 and guiding slideways 4.
The metal framework 2 utilizes two vertical and opposed uprights 5 and 6 which are fixed against the vertical wall faces of a wall of an industrial building in which wall an opening that is to be closed-off is made.
The opposed and vertical uprights 5 and 6 are connected together in the upper part of the handling door 1 by a motorized winding drum, not depicted, protected by a cover 7.
The winding drum is mechanically connected at one of its ends to a brake/geared motor assembly, not depicted, fixed in the upper part of a vertical upright 5, 6 and allowing the flexible apron 3 to be moved vertically between an open position and a closed position.
Each vertical upright 5, 6 comprises, on its outer face 8, a guiding slideway 4 formed, for example, of deformable elements 9, 10 allowing the flexible apron 3 and its horizontal crosspieces to be guided in their vertical movements between an open position and a closed position.
FIGS. 2 and 4 show only the vertical upright 5 of the handling door 1, given that the other one, 6, is generally identical in arrangement.
Thus, the vertical upright 5 comprises, on its outer face 8, ribs 11, 12 forming the device for sealing with the continuous edges 13, 14 of the straps 9, 10 of the guiding slideway 4.
It may be noted that the elements 9, 10 of the guiding slideway 4 are arranged between the ribs 11, 12 in such a way that the ribs 11, 12 are positioned and/or arranged outside the slideway.
The ribs 11 and 12 are designed to be continuous along the entire height of the slideway 4 and along the external profile thereof. However, the invention also contemplates that these ribs can be formed intermittently (not shown). In this case, the ribs would have small gaps between the projecting portions of the ribs.
The ribs 11 and 12 may be arranged parallel to each other or in the shape of a V, i.e., sloping towards each other, depending on the position of the elements 9, 10 of the slideway 4 on the outer face 8 of the upright 5.
The ribs 11, 12 allow each element 9, 10 of the slideway 4 to improve the sealing with respect to the upright 5 while at the same time allowing the straps the possibility of deforming when the flexible apron 3 is subjected to an abnormal lateral thrust.
The sealing device utilizes the ribs 11, 12 and is designed to suit all types of slideways 4, especially the types which are able to deform or to pivot with respect to the upright 5 when an external pressing force is exerted on the flexible apron 3.
It may be noted that the ribs 11, 12 arise from a shaping and/or bending of the outer face 8 of the upright 5 according to the position of the elements 9, 10 of the slideway 4.
It is apparent that the sealing of the flexible apron 3 within the elements 9, 10 of the guiding slideway 4 is achieved via ribs 11, 12 formed in each upright 5, 6 against which said elements of the slideway temporarily bear. Of course the ribs 11 and 12 can also have a shape that is different than that shown and can even be formed separately from the uprights 5 and thereafter attached by, e.g., bonding, fastening and/or welding.
It is noted that the foregoing examples have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the present invention. While the present invention has been described with reference to an exemplary embodiment, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Changes may be made, within the purview of the appended claims, as presently stated and as amended, without departing from the scope and spirit of the present invention in its aspects. Although the invention has been described herein with reference to particular means, materials and embodiments, the invention is not intended to be limited to the particulars disclosed herein. Instead, the invention extends to all functionally equivalent structures, methods and uses, such as are within the scope of the appended claims.
